Ubuntu Guest on Vista Host (Laptop Issue)

Description

This problem was already occuring in previous Virtualbox and still isn't fixed. So I want to know the status of it, and what Innotek / SUN is doing about it. (Previous ticket: http://www.virtualbox.org/ticket/1493)

To give it shortly. When I want to launch/install Ubuntu 7.10 on the Vista Home Premium guest it will get stuck at some point. Mouse and Keyboard is getting stuck ! And it seems that the whole system is getting frozen by it. Because Ctrl-Alt-Del won't even work then.

So please can this problem be fixed ? Or does anyone else know what the problem could be. Windows is working fine in Virtualbox but Ubuntu not ! The system is an: AMD Athlon x2 (64), 2GB Ram, ATI X1200 and o'course the OS: Windows Vista Home Premium (32). This problem isn't there on my normal PC !
